However when I replaced them I could hear the valve of the front tyre hissing and it completely deflated. Assuming a faulty valve I took it out and returned it for a replacement straight away but when I returned the back tyre had gone soft. To my amazement, even the replacement did the same.

Has anyone else had the same experience? Could I be doing something wrong. I only inflated them to 35psi using a compressor that I also bought in Aldi (plugs into the 12V supply in a car), could I have damaged the valves this way?

Do they have some sort of removable core for using sealant inside them? Only thing I can think of as I had that issue, albeit on a presta valve, as those ones do come loose and let air out. Otherwise maybe they were faulty, try pumping up with a hand pump. Not aware of any issues using a compressor as I've seen people doing bikes at petrol stations using that sort of valve

Thanks for the replies. I've also spoken with a couple people at work who said this just shouldn't happen out of the box. I don't want to throw good money after bad getting a valve tool but I may try twisting the cores in a bit more with some long nose pliers, could be they haven't been tightened properly. Good shout about the slime too, some did come out of one of the valves when it was expelling air.

I would nt take much notice about them being "puncture proof "..Get better tyres.
Informing the users that they are puncture proof would imply they would not need to carry a pump or a spare tube and means of exchanging the tube.
I have` nt had a puncture on any of my 23 mm skinny road racing tyres with no tread for over three years..And that is with the tyre pressures at over 100 lb with rock hard tyres.
I reckon this slime in the tyres is just a gimmick..Adds weight to the revolving wheels requiring more energy to rotate them... Does nt work well in car tyres neither and gave the EU the chance to add another useless energy saving device just to lower the overall weight of the car getting rid of the spare wheel

I would never be inclined to go for a budget inner tube. Pay a couple of quid more and buy a better brand from one of the large online cycling retailers. Plenty of product reviews on their website to pick something a bit better.

Get a bike second hand to save a big chunk of cash, but always go for high quality tubes and tyres.

Its proabably the most likely component of a bicyle to need replacing, and even the good ones are not expensive.

How this site works

We think it's important you understand the strengths and limitations of the site. We're a journalistic website and aim to provide the best MoneySaving guides, tips, tools and techniques, but can't guarantee to be perfect, so do note you use the information at your own risk and we can't accept liability if things go wrong.

This info does not constitute financial advice, always do your own research on top to ensure it's right for your specific circumstances and remember we focus on rates not service.

We don't as a general policy investigate the solvency of companies mentioned (how likely they are to go bust), but there is a risk any company can struggle and it's rarely made public until it's too late (see the Section 75 guide for protection tips).
